it decreases (check for instance the halogenes - F, Cl, Br, I, At)
Electronegativity decrease down in a group.
going down a group, electronegativity decreases going across a period, electronegativity increases
Iodine has a lower electronegativity than chlorine. Electronegativity generally decreases as you move down a group on the periodic table, so iodine, being lower in the halogen group than chlorine, has a lower electronegativity.
The trend in electronegativity among elements in the periodic table is caused by the attraction of an atom for electrons in a chemical bond. Electronegativity increases from left to right across a period and decreases down a group due to changes in atomic size and effective nuclear charge.
Carbon is a non metal.It is in the 14th group of the periodic table. Electronegativity of carbon is 2.5.
On the Periodic Table of elements, electronegativity increases as you move left to right across a period.
What group of people do anthropologists believe the most of alaska's native people are descended from?
Group 17 elements have the highest electronegativity out of which fluorine has the highest electronegativity.
The electronegativity increase across the period and down the group it itdecreases for non metals

Yes electronegativity changes along a period. It increases along a period.
